yum install -y golang

cd ~
go get github.com/mholt/caddy/caddy
go get github.com/caddyserver/builds 
go get github.com/caddyserver/dnsproviders/route53




vim /root/go/src/github.com/mholt/caddy/caddy/caddymain/run.go
# in this file, insert the following line to add in the tls route53 plugin: 

        _ "github.com/caddyserver/dnsproviders/route53"    # insert into the import block, just before the closing round bracket



cd /root/go/src/github.com/mholt/caddy/caddy
go run build.go


This should end up creating the following binary:

/root/go/src/github.com/mholt/caddy/caddy/caddy

you can then copy this into one of the paths, I suggest:

/usr/local/bin/caddy

The caddy rpm contains a *.service file. Once possibility is to install rpm, then replace the binary with the newly compiled 
binary.
